How to debug a Gluon Application that uses Dagger in Eclipse - eclipse

Question

I'm trying do create a JavaFX application based on Gluon. Therefor I'm using Eclipse with the Gluon plugin.
I need to say that I am new to Gradle and JavaFX as well, so maybe I disgrace myself with this question, because it's too obvious.
I created a fresh project with the Gluon project wizard that I am able to compile and start via the Gradle task "run". After some toying with the project I produced an error that I would like to debug step by step with the eclipse debugger.
So, how can you debug a Gluon/Gradle application? I'm also interested where I can configure the Gradle tasks. I see the preconfigured ones in the task list, but can only execute them by doubleclick. There isn't even a context menu. One idea was that there was a debug gradle task in the list, but I couldn't find one so far.
UPDATE:
I)
I need to add that I want to use Gluon ignite with dagger and my application can't be started by the eclipse run menu, because the code generation for the dagger modules has not been performed. Debugging and launching without Dagger seems to work. So my question is bit more specific than I thought...
